LID OR CLOSURE FOR RECEITACLES.

To all whom it may concern:

Be it known that I, VICTOR LOUGHEED, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Lids or Closures for Receptacles, of which the following is a specification.

This invention relates to closures, and while intended primarily for embodiment in the lid or cover for a receptacle, for ex ample, a lubricating cup or the like, it will be obvious that it is applicable to many forms of receptacles, housings, or the like, where it is desirable to have a movable closure.

The object of the invention is to provide a 'hingeless receptacle cover which, while greatly simplified in construction by the omission of hinging connections, pintles,;or other mechanism liable to become impaired, although, if desired, otherwise inseparably attached to the receptacle, will remain in either open or closed position until intentionally displaced. Accordingly, the primary feature of the invention consists in providing a hingeless cover, which, while adapted to lie in closing position upon the receptacle, is provided with a saddle, preferably upon its inner side, which is conposition upon the wall of the receptacle when the cover is open.

Still another featureof the invention consists in developing the embracing saddle upon the cover through the medium of an inward projection on the cover, preferably centrally located thereon, which, when the cover tilted outwardly and while the cover engages the outside of a wall of the receptacle, will rest upon said wall; also fulcrum Specification of Letters Patent.

member upon the inner side of the cover offset from the supporting projection sufliciently to bear against the inner side of the wall when the cover is supported in tilting o position and resisting the tendency of the cover to swing from tilted position to closingposition under the closing influence of gravity or its resilient connection with the receptacle, and thus holding the cover open until it is intentionally displaced from its wall-en1bracing position and per'mittedto assume closing position. 1

Another object is to adapt the cover to function as above described-when opened in different-directions to which end, a further feature of the invention consists in constructing thesupport in the-form of a short axial projectlon with the fulcruming member symmetrically extended in different radial directions therefrom, as, forinstance, j

by making it in the form of a polygonal or circularv disk concentric with the support. thereby developing 'a continuing annular edge embracing saddle between the disk and the cover. 1

Another object is to adapt the fulcruming' member to limit the opening of the cover; to which end said fulcruming member is connected with the support through the medium of an inclined surface through which it bears against the inner wall of the receptacle, as, for instance, by makingthe fulcruming member in the form of a pyramid or cone in those embodiments of the invention in which the cover is designed for open ing indifferent directions; the effect ofthis feature being to resist further outward turning movement after the cover has come into bearing ceptacle. I

In all forms of theinvention it is desirable to have a closing influence which tends to hold the cover upon the receptacle, this being in the form of a tension spring suitably anchored to the receptacle and attached 'to the cover in the line of its supporting on the exterior wall ofthe re- V is applicable.

may be of any construction or designed for anypurpose, for instance, a grease or oil cup, which may? be fattached through a threaded shank 2 to a machine part. T0 close the receptacle 1 a cover 3 is provided which is adapted to be held thereon either by gravity or through the medium of a spring 4L anchored at some suitable point, such, for instance, as through the loop 5 at the bottom ofthe receptacle. The cover 3 may be tilted in opposition to the spring f to gain access to theinterior of the receptacle 1, as, for instance, for recharging it with oil or grease; and in order that it may be supported in open position upon the edge of the receptacle 1, it is provided with a support 6, preferably in the form of an axial stud or projection, and a fulcruming member 7, which, when thecover is tilted to bringits support 6 into'bearing upon the edge of the'receptacle, will come into bearing against the inner wall of thereceptacle, as shown in Fig. 2, and so determine the direction of the inward moment developed by the spring 4 that it will be resisted by the bearing of the cover 2 against the edge of the-receptacle, and the cover will accordingly remain in open position until positively displaced by pressure at a decided angle to the direction of the springs influence, namely, by substantial. lateral pressure upon the upper side of the open cover. The fulcrum 7, support 6, and cover 3 together develop a wall -embracing saddle which resists tilting of the cover after it has been seated in tilted position upon the wall. The form of this saddle is preferably such that it limits the outward tilting or opening movement of the cover while resisting inward tilting or closing movement. By

continuing the fulcrum member 7 symmetrically around the support 6, the cover is adapted to function as described when opened in any direction. If the fulcrum member 7 is so developed as to pro- Fig. 2 is a View of the same with the cover plished by making the fulcrum member in the form of a cone, and the angle of the cone may be selected atywill to determine the tilting angle ofthe cover. 1

The cover may be provided with a marginal flange 8, as suggested in Figs. 1, 2, 3, 6, and 7, which will serve to prevent lateral displacement of the cover upon the receptacle, and which, suggested in Fig. 2, develops a fulcruming hearing at 8 in the function of limiting the outward tilting movement. Butas' suggested in Figs. 4 and 5, the cover may be made without the flange 8, the fulcrum member 7 being made of sufficient diameter to center the cover upon the receptacle, and-tl1 e outer edge of the receptacle. being beveled so as to establish a firm bearing and resist outward tilting, as suggestedlin Fig. 5. The spring may also be anchored otherwise than at the bottom of the receptacle,-as, for instance, through the medium of a diametric bar 5 (Figs. 4 and 5).

As suggested in Figs. 6 and 7 the cover need not be circular in form, but may be made polygonal, for example, square (Fig. 6) or hexagonal (Fig. 7).

The foregoing suggestions will besufrt cient to illustrate the application of the present invention.

I claim:
